Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by interrupting short-circuit currents quickly while allowing certain overloads to pass without blowing, ensuring selective and reliable protection.
Can this fuse be used in DC circuits?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
What is the purpose of the striker indication system?
The striker provides a mechanical indication that the fuse has blown, enabling quick visual identification and facilitating maintenance without the need for electrical testing.
Is this fuse compatible with standard Size 70 fuse holders?
Yes, it is designed to fit Size 70 fuse holders with clip mounting and plain blade terminals.
